​The human, animal, and environmental epidemiology of the emerging pathogen Cryptosporidium;
Development of an ultrastable measles vaccine for use where there are is no refrigeration or during emergencies;
the influence of malnutrition and environmental factors, such as air pollution and heavy metals, on common infectious diseases such as diarrhea and pneumonia.
Dr. Griffiths has a long interest in waterborne diseases, ranging from research on the biology of the pathogens to their epidemiology and to public policy and regulation.
